Benefits of technology

[0006] It is the primary objective of the present invention to provide an exercise treadmill, which enables the treadmill frame to be received in the non-operative position or adjusted to the desired angle of inclination by means of an electric control.
[0007] It is another objective of the present invention to provide an exercise treadmill, which provides a self-locking function during turning of the treadmill frame, ensuring a safety use.

Problems solved by technology

This manual design is suitable for a small scale exercise treadmill, not practical for use in a big scale exercise treadmill.
A mistake during operation may cause the treadmill frame to fall, resulting in an accident.

Embodiment Construction

[0015] As shown in FIGS. 1 and 2, an exercise treadmill provided by a preferred embodiment of the present invention is shown comprised of a base frame 10, a treadmill frame 20, a locking mechanism 30, two crank arms 40, and a lifting mechanism 50.

[0016] The base frame 10 is a rectangular open frame formed of metal rod members by welding for placing on the floor. The base frame 10 comprises an upright 12 upwardly extended from the top near the front side for holding by the user using the exercise treadmill, a control panel 13 mounted on the upright 12, a retaining member, namely a lug 14, at the front side of the upright 12, and two upright sidewalls 15 bilaterally longitudinally disposed at the front left and right sides. The sidewalls 15 each have a vertically extended guiding slot 16 and a sliding slot 17 horizontally forwardly extended from the bottom end of the guiding slot 16 to the periphery of the sidewall.

[0017] The treadmill frame 20 is mounted on the base frame 10, havin...

Abstract

An exercise treadmill includes a base frame, a treadmill frame having a front side detachably connected to the base frame, a locking mechanism for locking the front side of the treadmill frame to the base frame, two wheeled crank arms pivoted to the treadmill frame, and a lifting mechanism. The lifting mechanism has a motor and a transmission unit coupled to the motor and the crank arms for lifting or lowering the front side of the treadmill frame after unlocking of the locking mechanism or for lifting or lowering a rear side of the treadmill frame after locking of the front side of the treadmill frame to the base frame by the locking mechanism.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an exercise treadmill and more particularly, to an exercise treadmill having a fold-up capability and a front that is adjustable in the vertical direction. [0003] 2. Description of the Related Art [0004] A conventional exercise treadmill essentially includes a base frame and a treadmill frame. The base frame is placed on the floor, having an upright upwardly extended from the front side for holding by the user walking on the treadmill belt of the treadmill frame. In order to simulate walking on a slope, the treadmill frame is provided with a locating hole on the front side for connection to one of a vertical row of locating holes at the front side of the base frame selectively by a lock pin. After use, the user can lift the rear side of the treadmill frame and receive the treadmill frame to the upright of the base frame to reduce space occupation. [0005] This manual design is suitabl...
